what is inside mars???
Answers
If Mars is comparable to Earth, it probably has a solid core. Mars is so much smaller than Earth that if it were created in a similar way, of similar materials, its core should have cooled and solidified by now. But other indirect evidence suggests that Mars is more than simply a smaller Earth. Samples of Martian meteorites, the lack of a magnetic field, and the way the planet moves as it orbits the sun, all suggest a different sort of planet altogether. Moreover, long-term observations of how the sun’s gravity subtly shapes the planet at different phases of its orbit (think tides without an ocean) suggest that Mars may actually have a liquid core. The debate can’t be resolved, however, without more precise data from InSight.
